The short, triumphant, tragic career of Phil Ochs illustrates one of the harder lessons of American popular culture: that audiences are moved far more by mystery than by commitment. Of all the artists of the 1960s folk-music boom, only Bob Dylan understood that in his bones, and only Dylan became a superstar. Ochs, by contrast, was the bright class president of the Greenwich Village scene, reeling off powerful, didactic protest songs in an earnest tenor. He was direct and defiantly uncool, and it doomed him.
